SLANT 'BOARD` FOR PRINTING-PRESSES, 80C.

SPECIFICATION forming part of Letters Patent No. 738,967, dated September 15, 1903.

Application led J' une 25, '1962.

To all whom it may concern:

Be it known that I, GEORGE R. WILLIAMS, a citizen of the United States, and a resident of Brooklyn, in the countyy of Kings and State of New York, have invented a new and useful l Improvement in Slant-Boards for Printing- Presses, &c. of which the following isa speciiication.

This invention relates to the slant-boards which are arranged upon the main feed-boards of printing-presses, paper-feeding and other vmachines at the delivery end of the main feedboard, and particularly to that kind of slantboards which are composed of a transverse series of metallic 'ng'ers or blades, each arranged lengthwise of the feed-board. These fingers have been secured at their upper ends to a transverse bar or rail by detachable fastenings, such as screws. y

The objects of this invention are to provide simple means for attaching the fingers to the supporting bar or rail, which means enables the fingers to be readily attached or detached and to be adjusted laterally on the bar or rail, as the width of the sheetsor other conditions may require or render desirable, also to irnprove the attaching devices in other respects.

In the accompanying drawings, Figure lis a fragmentarytop plan view of my improved slant-board. Fig. 2 isafragmentary top plan view of one end of the slant-board on an en- Fig.A 3 is a longitudinal section through one of the intermediate fingers of the slant-board in line 3 3, Fig. 2. Fig. 4 is a perspective view of one of the intermediate fingers. Fig. 5 is a fragmentary perspective view of the supporting bar or rail. Fig. 6 is a sectional side lelevation of one of the end fingers, the section being taken in line 6 6, Fig. 2. Fig. 7 is a cross-section of one of the end iingers in line 7 7, Fig. 2. Fig. 8 is a perspective v-iewof one of the end fingers.

Like letters of reference refer to like parts in the several figures.

-Ay represents the main feed-board of a printing-press, paper-feeding machine, or other machine.

B represents a transverse supporting bar or rail arranged above the feed-board near Serial No. 113,119. (No model.)

the delivery end thereof, and B represents a similar' bar arranged parallel to the bar B in rear of the latter. The bar B is somewhat lower than the bar B and the two bars form together the transverse channel in which vthe side-registering mechanism (not shown) is arranged. The bars B B are secured at each-end to a supporting-bracket h, carried by the feed-board. The front supporting-bar B is provided on its rear side, the side which is turned toward the delivery end of the feedboard,with a transverse guide C, which is preferably formed separately from the supporting-bar and secured thereto by riveting or otherwise. The guide C is provided on its face with an upper horizontal rib c, having a horizontal top o which is arranged slightly below the top of the supporting-bar, and with an overhanging or dovetail lower side c2, forming the top of a dovetail groove c3, below which the guide C is provided witha horizontal rib c4, having horizontal upper and lower sides.

The supporting-bars B B preferably have the form of angle-bars, as shown.

D represents the fingers, which are preferably formed each of a narrow steel plate and provided at the base or attaching end with a Vclip or shoe E, by which the finger is attached to the supporting -'bar. This clip and the guide C ofthe supporting-bar vare so' shaped and constructed that the clipcan be engaged with the guide and moved along the sameto the position which the finger is desired to occupy. To this end the face of the clip is provided with an upper horizontal rib e, having horizontal top and bottom sides, a groove e.'

below said rib, and a lower rib e2, which has a dovetail upper face and is divided at or near its middle into two parts or lugs by a notch or space f, while the upper rib c of the guide C is provided at one or more points of its length. with a pair of notches f' pf the proper length to permit the ribs or lugs e? of the clip to be passed downwardly through these notches. Upon placing the finger with its clip upon the guide, with the ribs or lugs@2 of the nger standing above the notches f of the guide, the clip can be pushed down until the dovetail ribs c2 of the clip stand in line with the dovetail groove c3 of the guide. The finger, can :now besnioved along the guide, whereby the lugs of the finger are moved away from the notches of the guide and the finger becomes securely attached to the guide and supporting-bar. The finger can be readily shifted along the bar to the desired position and can. be readily removed from the bar upon placing its lugs in line with the notches of the guide and .moving the clip upwardly.

The clips arepreferably made of east metal and secured to the fingers by riveting.

g is a plate-sprin g which extends rearwardly from the clip below the finger and which is secured at one end to the clip by riveting or otherwise and bears with its other free end upon the rear bar B. shape that it is strained by attaching the finger to the supporting-bar and this tension of the spring holds the finger snugly in place and prevents rattling. The spring, however, permits the finger to be readily raised out of engagement with the guide.

VEach end finger D is preferably made somewhat wider than the intermediate fingers D in order to provide a wide support for the edge of the sheet and is provided at its outer side with a short auxiliary or stub finger D2.`

The latter does not extend to the supportingbar in order to leave freespace above this stub-finger for parts of the side-registering mechanism, but is supported from the end finger D by a transverse bar g', which is preferably somewhat depressed below the level of these ngers.

My improved attaching means permits eahc linger to be easily attached to or removed vfrom the supporting-bar and to be adjusted laterally on the kbar to the desired position. In changing from one size or kind of sheets ,to another it is sometimes necessary or desirable to arrange the fingers more closely together and to increase the number of fingers correspondingly or to spread the fingers farther apart and to remove some of the fingers. My invention provides means for doing this conveniently and quickly. The attaching means is also very convenient, because the fingers and theirsupporting parts contain the attaching means, and separate fastening devices, snch as screws, are dispensed with.

I claim as my inventionl.
